Pelican creating undefined setting `STATIC_LANG_SAVE_AS` raises an error

[ungual]

Hello,

I'm working on a multilang Pelican website. I want the first folder after content/ to be passed as the lang metadata, and the rest of the folders to be the category (here using nested categories with the more-categories plugin). So an article placed in fr/event/2022/my-event.md has lang = fr, and category = event/2022.

In order to do so, I'm using the PATH_METADATA settings to extract them using the following regex:

PATH_METADATA = '^(?P<lang>.+?)\/(?P<category>.*)\/.*'

Pelican write the output articles and pages as it should, but at the step of cloning static content it encounters an error. If I remove static content at all (STATIC_PATHS = []), then everything generates perfectly. But if i had back the images (STATIC_PATHS = [images]), then i get this error:

CRITICAL: 'STATIC_LANG_SAVE_AS'

which is weird because this setting does not exist. I figured out it was happening while calling the _expand_settings function at line 215 of content.py in the source file, creating this non-existing setting by merging two variables (klass and key).

I was able to bypass this issue by declaring them in the pelicanconf.py like this

STATIC_LANG_SAVE_AS = STATIC_LANG_URL = '{path}'

but this feels so wrong.

Anyone has an idea of what causes this _expand_settings function to be called with klass = STATIC and key = LANG_SAVE_AS and creating this non-existing setting? Could it be that PATH_METADATA is applied to images, giving them a wrong lang attribute in this configuration which is latter calling for a key = LANG_SAVE_AS with klass = STATIC ?

Can you share the full traceback by running pelican with --debug?

yes of course, here it is

It's called with 'save_as' as expected, so... it appears like you have a Static_Lang class that's replacing the built in Static class? That is odd, I'm not sure where that's coming from. PATH_METADATA should not have any effect. I'd suspect a plugin to be the culprit. Can you show your config file?
